1 / 8 page MOTOROLA CMOS LOGIC DATA 1 MC14561B 9's Complementer The MC14561B 9’s complementer is a companion to the MC14560B NBCD adder to allow BCD subtraction. A BCD number (8–4–2–1 code) is applied to the inputs (A1 = 20, A2 = 21, A3 = 22, A4 = 23). If the complement control (Comp) is low, the BCD number appears at the outputs unmodified. The complement disable (Comp) allows the complement control to be gated, or an inverted control signal to be used. If the complement input is high and the disable input low, the 9’s complement of the number is displayed at the outputs. The zero control (Z), when high, forces the outputs low regardless of the state of the other inputs. When the MC14561B is used to perform BCD subtraction in conjunction with the MC14560B NBCD adder, the complement control becomes an add/subtract control. • All Inputs Buffered • Supply Voltage Range = 3.0 Vdc to 18 Vdc • Capable of Driving Two Low–Power TTL Loads or One Low–Power Schottky TTL Load Over the Rated Temperature Range MAXIMUM RATINGS* (Voltages Referenced to VSS) Symbol Parameter Value Unit VDD DC Supply Voltage – 0.5 to + 18.0 V Vin, Vout Input or Output Voltage (DC or Transient) – 0.5 to VDD + 0.5 V Iin, Iout Input or Output Current (DC or Transient), per Pin ± 10 mA PD Power Dissipation, per Package† 500 mW Tstg Storage Temperature – 65 to + 150 _C TL Lead Temperature (8–Second Soldering) 260 _C * Maximum Ratings are those values beyond which damage to the device may occur. †Temperature Derating: Plastic “P and D/DW” Packages: – 7.0 mW/ _C From 65_C To 125_C Ceramic “L” Packages: – 12 mW/ _C From 100_C To 125_C TRUTH TABLE Z Comp Comp F1 F2 F3 F4 Mode 0 0 0 0 0 1 A1 A2 A3 A4 Straight–through 0 1 1 0 1 0 A1 A2 A2A3 + A2A3 A2A3A4 Complement 1 X X 0 0 0 0 Zero X = Don’t Care. MOTOROLA SEMICONDUCTOR TECHNICAL DATA © Motorola, Inc. 1995 REV 3 1/94 MC14561B This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, pre- cautions must be taken to avoid applications of any voltage higher than maximum rated volt- ages to this high–impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS v (Vin or Vout) v VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. L SUFFIX CERAMIC CASE 632 ORDERING INFORMATION MC14XXXBCP Plastic MC14XXXBCL Ceramic MC14XXXBD SOIC TA = – 55° to 125°C for all packages.
